What If- Eye-glasses as view-finder for photography

Amateur photographers had struggled for decades through the view finder in the cameras before the LCD screen display arrived in the digital cameras. It made taking photos very easy for amateurs. However, seeing through the view-finder or LCD can be a struggle at times when you try to focus. The LCD screen may not be as bright in the sunlight. What if there were eye-glasses which could be connected with the camera through a remote control allowing the photographer to see the image exactly as it would show on in final print. It might be awkward in the beginning because with these glasses you will have to turn your camera not your neck to see what else is around. At the same time, it will have the thrill of seeing the image as it would appear exactly, without losing time in trial and error.
